United States Patent 3,211,149 BODY CAVITY TREATING APPARATUS LouisFolio, Central Islip State Hospital, Central Islip, N.Y. Filed Mar. 27,1962, Ser. No. 182,880 3 Claims. (Cl. 128-232) This invention relates toportable apparatus or devices for treating body cavities, such as theoral cavity, with treating fluids, and more particularly to an improvedapparatus of this type whereby the fluid may be supplied to the cavity,in controllable quantities, and kept there for a desired period of time,with the used fluid being drained from the cavity independently of thesupply of fresh fluid thereto.

It is an object of this invention to provide portable body cavitytreating apparatus which is simple and easy to operate, easily appliedto the respective cavity, and particularly adapted for using smallquantiies of expensive ingredients.

Another object of the invention is to provide such apparatus including acontainer for fresh fluid and a container for drained fluid, togetherwith independent means for supplying fluid from the supply container tothe body cavity and independent means for draining fluid from the bodycavity.

A further object of the invention is to provide apparatus of this typeincluding a plurality of different applicators and a plurality ofdifferent supply and drain assemblies, in which any applicator may beused with any supply and drain assembly.

A still further object of the invention is to provide apparatus of thistype which is appropriately contoured or shaped to fit the body cavityto which it is applied.

A specific object of the invention is to provide flushing or cleansingapparatus for the mouth, and which is shaped to readily fit over theteeth and the gums.

FIG. 16 is a perspective view of still .another modified form ofapparatus embodying the invention.

Referring first to the embodiment of the invention shown in FIGS. 1, 2and 3, an applicator, generally indicated at 15, is illustrated asconnected to a supply tank with which is associated a drain or returntank 25. As best seen in FIGS. 2 and 3, the applicator 15, in thisembodiment of the invention, is generally U or horseshoeshaped in plan,and has a generally H-shape cross section. The applicator 15 is intendedfor flushing the teeth and gums, and is therefore made to have agenerally conforming fit over the teeth and gums. It may be made of anysuitable material, and preferably is made of a plastic compositionmaterial which may be resilient or flexible to accommodate itselfconformingly to the teeth and gums.

As best seen in FIG. 3, applicator 15 is formed with a hollow centralpassage 16 extending therearound, and is formed with oppositely directedapertures 17 which are spaced along the passage 16. Passage 16communicates continuously with the hollow walls or flanges 18 of thedevice 13 and these hollow walls, on their inner surfaces, are formedwith apertures 19 for flushing the sides of the teeth and gums.

A supply pipe 21 provided with a shut-off cock 22 connects passage 16 tosupply tank 20. A drain pipe 26, having an inverted and perforated inletend 27, connects with the drain container or tank 25. The inverted J-shaped inlet end of the pipe 26 is arranged to extend over the lip ofthe user and into the lower portion of the mouth. A bafl le 23 isprovided at the rear of the applicator 15 to divert fluid from thethroat.

The supply and drain tanks 20 and may be formed of a plastic materialwhich is resilient and flexible so that the outer walls of these tanksmay be compressed. The two tanks are preferably formed as a unitprovided with a rigid interior common separating partition 14.

The arrangement operates in the following manner. Cock 22 is opened andthen either the outer wall of tank 20, or the outer walls of both tanks20 and 25, are squeezed or compressed against the rigid partition 14.This forces the flushing or cleaning fluid 23 through the pipe 21 intothe applicator 15 and outwardly through the apertures thereof intotreating or washing relation with the teeth and gums. 'Io drain thefluid from the mouth, the cock 22 is closed and the pressure on thetanks 24 and 25 is released. Alternatively, if only tank 20 has beencompressed previously, tank 25 is compressed and released. This createsa vacuum within the drain tank 25 so that fluid in the mouth is suckedinto the drain tank. The operation may be repeated, as described, asoften as is necessary for thorough treating of the gums and teeth, aswell as for flushing of the oral cavity.

Referring to FIG. 4, a modified form of arrangement is shown involvingan applicator in the form of a perforated head which may be insertedinto a body cavity. Head 30 is connected by a pipe 31 to a bent pipe 39having branches 32 and 33. Branch 32 is connected to a feed tank orcontainer 34 and branch 33 is connected to a drain tank or container 36.The latter are in the form of flexible bulbs which may be squeezed toprovide either pressure or a vacuum.

In this embodiment, the direction of flow is governed by a ball checkvale positioned in pipe 39 in such a manner as to bar access of ballvalve 35 into pipes 31, 32 and 33, but allowing it to move between seats28 and 29 at the ends of pipe 39. When supply bulb 34 is pressed, thepressure forces ball valve 35 to engage seat 28 to block drain pipe 33so that fluid will flow through pipe 31 into applicator 31) from whichit will be discharged through the apertures therein. The supply of fluidwill stop when pressure on supply bulb 34 is released, and the resultantsuction in supply bulb 34 will cause a reverse flow moving ball valve 35to engage seat 29 to prevent any used fluid flowing into the supply bulb34.

The body cavity may be drained by pressing the drain bulb 36 and thenreleasing it to provide a vacuum which will cause the fluid to be drawnfrom the applicator through pipes 31, 39 and 33 into drain bulb 36. Bychoosing the difference in height 11 between seats 28 and 29, and thecurvature of pipe 39, so that, with the apparatus held in asubstantially vertical position during the draining operation, thevacuum created by the expanding drain bulb 36 cannot lift valve 35 fromseat 29 to engage seat 28. The ball valve 35 will therefore remain inclosing relation to supply bulb 34 and the drained fluid is thusprevented from flowing into the supply bulb 34.

In the arrangement shown in FIGS. through 9, the supply tank 48 isshown, solely by way of example, as pressurized, and its outlet 41 isconnected by a supply pipe 42 to an applicator 34) which is shown,purely by way of example, the same as the applicator 30 of FIG. 4.However other applicators differing from the applicator 30 may be used.A valve 43 operated by a spring biased pivotally mounted handle 44normally blocks flow through the pipe 42 but, upon swinging movement ofhandle 44 in a clockwise direction, the valve 43 is opened so that itsaperture 38 is coaxially aligned with the pipe 42.

In this case, the drain tank 45 is in the form of a collapsible bellowswhich is normally spring biased to expand into a framework generallyindicated at 46. The drain tank 45 is provided with a drain pipe 47which has an inverted end 48 quite similar to the end 27 of the drainpipe 26 of FIGS. 1, 2 and 3. The drain tank 45 is biased to the fullyopen or expanded position, illustrated in dotted lines in FIG. 5, bysprings 48, 49, 45', which are tension springs connected at one end tothe wall of framwork 46. The upper end of each spring is connected to arelatively elongated shank element 11 having a ring at its upper end and21 preferably cylindrical enlargement 12 intermediate its ends as seenin FIGS. 8 and 9. The springs of each set 49, 49', or 49 are arrangedpreferably at equal angular distances from each other circumferentiallyof the framework 46, as best seen in FIG. 6.

As shown in FIG. 5, the collapsing takes place in three or more stages.In the particular embodiment shown in FIG. 5, there are two sets ofvertically aligned springs 49 and 49", the springs 49 controllingmovement from the fully closed position of the tank 45 to the end of thefirst expansion stage and the springs 49" controlling movement of thetank 45 to the fully open position from the end of the second expansionstage. A third set of springs 49' is angularly spaced from the springs49 and 49", and controls expansion of the tank 45 through the secondexpansion stage. While three stages are illustrated, it will beunderstood that as many stages may be provided as is necessary ordesirable, and it should be noted that the springs controlling movementor expansion of the tank 45 in the even numbered stages are alignedvertically with each other, but these springs are angularly offset fromthe springs controlling expansion of tank 45 in the odd numbered stages,which latter are also vertically aligned with each other.

At each spring location, angle irons, such as 156, 156', and 156", aresecured to the framework 46 to extend vertically thereof. The angleirons 156 extend through the first stage of expansion of the tank 45,the angle irons 156' extend through the second expansion stage, and theangle irons 156" extend through the third stage of the expansion of tank45. It will be noted that the angle irons 156 and 156 are verticallyaligned with each other, whereas the angle irons 156 are angularlyoffset from the angle irons 156 and 156". Each angle iron has one legsecured to the framework 46 and the other leg 155, 155, or 155"extending inwardly of the outer periphery of a control ring 37. Securedto each angle iron leg attached to the framework 46 is a guide 13 in theform of a pipe receiving the cylindrical extension 12 and having slots14 to receive the shank element 11, as best seen in FIGS. 8 and 9. Theinwardly extending leg of each angle iron 156, and correspondingly ofthe other angle irons, cooperates with notches 158 in the outerperiphery of control ring 37, these notches normally being disposed atthe central position illustrated in dotted lines in FIG. 7. At equalangular distances from notches 158, control ring 37 is provided withradially extending hooks 157 and 157', the hook ends of which extendingin opposite circumferential directions.

If control ring 37, which is rotatable relative to the bottom of tank45, is rotated clockwise an amount sufficient to align its solts 158with the arms 155 of angles 156, the hooks 157 will move thecorresponding shanks 11 and enlargements 12 out of the guides 13 andwill engage in rings 10. The springs 49 are therefore released to pullthe control ring 37, and thus the bottom of the tank 45, downwardly to aposition where the control ring 37 will engage the upper ends of legs155' of angle irons 156'. If the control ring 37 is now rotatedcounterclockwise to bring the slots 158 back to their central position,the shanks 11 and enlargements 12 associated with rings 10 will beengaged in the pipe guides 13 arranged at the lower end of the angleirons 156, so that the springs 49 will be held in this position. Toeffect a further expansion of tank 45, the control ring 37 is nowrotated counterclockwise from its central position so that slots 158 arealigned with the legs 155' of the angle irons 156'. In such movement,the hooks 157 will move the enlargements 12 out of the pipe guides 13and will engage the rings 10 of the shanks 11' associated with thesprings 49, so that the ring 37, and thus the bottom wall of the tank 45may be moved downwardly through the second stage by the springs 49. Theoperation is then repeated as often as is necessary to expand the tank45 through all the stages. It will be appreciated that the stepsdescribed, and in the reverse sequence, are utilized in recompressing orcollapsing the tank 45. Expansion of the tank 45, of course, withdrawsfiuid from the body cavity, through the inlet 48 of the drain pipe 47.It will be noted that, in the arrangement of FIG. 5, as well as in thoseof FIGS. 1 through 4, the supply tank and the drain tank are completelyindependent of each other so that the fluid may be supplied and drainedas independent operations.

FIGS. 10 and 11 illustrate another embodiment of the invention in whichthe drain tank and the supply tank are completely independent of eachother so that the fluid supply and fluid draining operations may"likewise be carried out independently. Referring to these figures, boththe supply or feed container or tank 50 and the drain container or tank55 are flexible impermeable bellows which are preferably wedge shaped inelevation. The bellows of feed tank 50 is arranged between an outer flatwall 51 and a rigid central wall 52, the plate 51 being pivoted, at itslower end, to the wall or plate 52. Similarly, the bellows comprisingthe drain tank 55 is disposed between an outer wall plate 53 and thecentral wall or partition 52, plate 53 being likewise pivoted, at itslower end, to the lower end of the central partition 52. A supply pipe54 connected to the feed tank 51 may have a suitable applicator (notshown) connected to its outer or discharge end.

Similarly, a drain pipe 56 is connected to the drain tank 55 and mayhave its outer, or inlet end, connected either to an applicator orformed as shown at 27 in FIG. 1 or 48 in FIG. 5. An arcuate rack 57, ora pair of arcuate racks 57, are secured to the central partition 52adjacent its upper end to extend substantially at right angles thereto.The walls 51 and 53 are provided with operating knobs 58 and 59,respectively, releasably cooperable with the racks 57.

In operation, the knob 58 associated with plate 51 may be lifted and theplate 51 may be moved toward the central partition 52. This will forcefluid from the feed container 50 through the pipe 54 to the applicatorfor discharge into the body cavity. It will further be noted that thisoperation is entirely independent of any operation of the drain tank 55.During pressure operation of the feed tank 50, the drain tank '55 ismaintained in the collapsed condition illustrated in solid lines in FIG.10, or in case of use in stages, in any partly expanded condition. Todrain fluid from the body cavity, the knob 59 associated with the plate53 is lifted from the associated rack 57 and the drain tank 55 isexpanded. This creates a vacuum which will drain fluid from the bodycavity through the drain pipe 56 into the container 55. During thislatter operation, the feed tank 50 is preferably latched in the fully orpartially collapsed condition.

In connection with the foregoing description, it should be noted thatany of the described drain tank and feed tank assemblies are usable withany of the applicators, and that any drain tank may be used with anyfeed tan-k. Thus, either or both of the tanks may be flexible orcollapsible and have a common rigid Wall, but work by alternatingpressing either the supply tank or the drain tank, with or without checkvalves and either hand or spring operated. Thus, bellows arrangements ofthe types shown in FIGS. and 11, or of the cylindrical type, may be usedfor either or both of the supply tank and the drain tank. Also, pistonoperated feed and drain tanks may be used.

FIGS. 12 and 13 illustrate an applicator particularly adapted fortreatment of the teeth. This applicator, generally indicated at 60,includes upper and lower reversely directed applicator elements 61 and62 which are generally U-shaped in cross section so as to fit closelyaround the upper and lower teeth. The bases of the two U-shaped sectionsare pivotally interconnected by a nipple 63 which opens through bothbases. The inner surfaces of the side Walls of each section are providedwith bristles 54, and such bristles may also form an annular brusharound each discharge end of nipple 63. Nipple 63 is connected to a feedpipe 65 whose inlet end may be connected to any one of the several feedor supply containers illustrated and previously described. Thearrangement further includes a drain pipe 66 which may have a bent endand be formed similarly to the drain pipes 26 and 47 of FIGS. 1 and 5.Drain pipe 66 has its outlet end connected to any one of the draincontainers shown in FIGS. 1 through 11.

The device 60 may be moved back and forth along the teeth giving abrushing or wiping action thereon, depending upon whether it is providedwith bristles 64 or with sponges (not shown) in place of the bristles.During this time, the feed container is operated to supply cleansingfluid through the feed pipe 65 and thus into the nipple 63 from which itis discharged at each end into the interior of the sections 61 and 62.At any time, or at the end of the cleaning operation, the drain tank maybe activated to withdraw used fluid through the drain pipe 66 into thedrain container. The feed pipe has a rigid portion so that it may beused as a manipulating handle.

FIG. 14 illustrates a modified form of the arrangement shown in FIGS. 12and 13, and which is formed of an elastic or flexible material. In thisinstance, the applicator 60 also includes upper and lower sections 61'and 62 but these are interconnected, at their inner ends, by arelatively solid partition 67 which is integral with the sections 61'and 62' and made of the same material. The bases of the sections 61' and62' are again pivotally connected to the ends of a nipple 63' openingthrough both bases, and the feed pipe 65' is connected, in communicationrelation, with the nipple 63'. The applicator 60 of FIG. 14 is otherwisesubstantially identical to the applicator 60 of FIGS. 12 and 13.

FIG. illustrates an applicator particularly adapted for flushing andrinsing, or otherwise fluid treating, the oral cavity. This applicator,which is generally indicated at 70, includes a frame or mask 71, whichmay be made of flexible material, and which maybe adhered to the face bysuitable pressure sensitive adhesive or which may be held in position bythe hand as illustrated. A bag or sack 7 2, of impermeable material, ispreferably integral with the mask 71 and opens therethrough.Alternatively, bag or .sack 72 may be sealed in fluid-tight relation tothe mask or frame 71. A feed pipe 73 extends in fluid-tight relationinto the interior of the bag or sack 72 and has an applicator 74,similar to the applicator 30, on the inner end thereof and which mayextend into the mouth. vA drain pipe 75 is also connected to the sack72. Feed pipe 73 may be connected to any one of the feed or supplycontainers previously described, and drain pipe 75 may be connected toany one of the drain containers previously described, for independentoperations of supplying fluid to the oral cavity and of draining fluidtherefrom. This embodiment of the invention, as well as otherembodiments thereof when provided with suitable applicators, may be usedin treating the genital organs, such as the vaginal cavity.

FIG. 16 illustrates [another arrangement for flushing the oral cavity.In this case, there is a rigid or substantially rigid frame 81 which isheld between the lips by pressure thereon. A bag or sack 82 opens influid-tight relation through the frame 81 for communication with theoral cavity, and .a feed pipe 83 extends into the .bag or sack 82 andinto the oral cavity, this feed pipe likewise being in fluid-tightrelation with the bag or sack 8 2. A drain pipe 84 is connected influid-tight relation to the sack or bag 82. The arrangement otherwiseoperates in exactly the same manner as previously described, particularly for FIG. 15

While specific embodiments of the invention have been shown anddescribed in detail in order to illustrate the application of theprinciples of the invention, it will be understood that the inventionmay be embodied otherwise without departing from such principles.
